To all whom t may concern.'

Be it known that I, ALEXANDER W. Cor LAND, a citizen of the United States of America, residing at Detroit, in the county view of the apparatus; Fig. 2 is a longituf 1"1 dinal section thereof; and F ig. 3 is a cross section.

A is the tank'containing the fat, which is heated by suitable means, such as a gas burner B.

C is a frame adapted to be vertically reciprocated into and out of said tank, and,v

as shown, comprises theside members D connected by a rod E and secured to the vertical guide rods F, which' slidably engage bearings G at the sides of the tank.

H are dough-carrying trays detachably engaging the frame C preferably by engaging guide grooves .I in the opposite side members D thereof.

J is a perforated screen extending across the frame above the plane of the guides I and adapted to hold the dough beneath the surface of the liquid while frying.

K is a rock shaft having rock arms L thereon at opposite sides of the frame connested by links M to the vertical guides F, and N is af pedal lever for actuating the rock shaft to raise and lower the frame, said lever also constituting a counterweight for balancing the frame.

C is a rearwardly-extending frame having guides P thereon in alinement with the guides I and adapted to receive the trays r' after completion of the frying.

With the construction as thus far de` scribed, in use the operator places a tray filled with the dough cakes for frying in engagement with the guides I and pushes it inward into a position over the tank. The frame C is then lowered into the liquid which immerses the tray and dough cakes thereon. These cakes when first immersed are of greater specific gravity than the liquid and will sink therein, but, as soon as they become expanded by cooking, become less 1n specific gravity than the liquid and will rise to the surface. Thus there is danger of disarrangement of the cakes due to eo the fioating of one over another, and this would. interfere 'with the uniformity of the cooking and would otherwise be objectionable. I have, therefore provided means for avoiding this result, as follows: Vhen the c5 frame C is first lowered into the fat, its downward movement is limited to a point where the dough cakes are not deeply immersed. This position is maintained until the swelling of thel cakes renders them of lesser specific gravity than the liquid, but,r .due to the fact that they are not deeply ilij;`

mersed, the cakes will not fioat one under the other or out of position. The frame is then depressed to a greater distance, which will cause the screen J to engage with the tops of the cakes and depress thembeneath the surface of the liquid. In this operation there is no displacement of the individual cakes, all will be simultaneously seated upon the tray in the same position originally occupied. Any suitable construction of means may be employed for temporarily arresting the downward movement of as shown, the rock shaft K is provided with a segmental arm Q, having a notch R, therein for engaging a latch detent S, this being connected by a rod S with an operating handle T. The notch R that the latch engages the same, when the frame C is first depressed into the proper position for the first frying` operation. After a suitable time interval the operator lifts the handle T to disengage the detent a5 and permit the further lowering of the frame and the complete immersion of the cakes.

After the completion of the frying operation, the frame C is again raised by the de- 100 pression of the lever N with the foot, and the latch R engaging a shoulder U on the segment Q. will hold the parts in this position. The operator then inserts another tray having doughfcakes thereon into en- 105 gagement with the guides I and moves this tray inward, the tray having the fried cakes will be displaced and pushed onto the guides P from which place it may be removed.

The tray of fried cakes are allowed to cool l1@ and, upon the raising of the frame.

the dough, but,

is so positioned on guides P, so that the surplus fat may drip into the pan O from which it will drain directly into the tank.

What I claim as my invention is:

1. The combination With a tank, of a frame vertically adjustable into and out from said tank, a screen extending h0rizontally across said frame, a dough supporting tray detachahly engaging guides beneath said screen, means for raising and lowering said frame, and means for temporarily arresting said frame after a partial lowering thereof permitting the further lowering of the tray.

2. The combination with a tank, of a supporting tray depressible into said tank, a superimposed screen, means forl temporarily arresting the depression of said tray, and means for moving said arresting means to an inoperative position to permit of further depression of said tray. A

3. The combination with a tank, of a supporting tray depressible into said tank, a superimposed screen, means for depressing said tray into the tank, means for temporarily arresting the depression of said tray, and means for moving said arresting means to an inoperative position to permit of further depression of the tray.

4. The combination with a tank, of a frame vertically adjustable into and out of said tank, a dough supporting tray detachably engaging said frame, a superimposed screen, means for temporarily arresting the depression of said tray permitting the further depression thereof.

5. The combination with a tank, of a supporting tray depressible into said tank, means Jfor temporarily locking said tray at a predetermined point in the path of its depression, and means for disengaging said locking means to permit of further depression of the tray.

In testimony whereof I a'HiX my signature vin presence of tWo Witnesses.
